Gadolinium Magnet Generator.

interesting thought, synchro1.
Although using this material gives lots of possibility, in the end I doubt that the energy required to control the heat transfers that a 'motor' would need, is less than than any output obtained. It's a bit like Maxwell's Deamon'?
Still, interesting.

Researching MCE I found the effect is practically "Instantaneous" and "Reversible"!

"Magnetic refrigeration is based on the Magnetocaloric Effect (MCE). The MCE implies that the temperature of suitable materials (Magnetocaloric Materials, MCM) increases when exposing to a magnetic field and decreases when it stops.

"The temperature to which this effect is the strongest (the Curie temperature) depends on the properties of every material. The effect is reversible and almost instantaneous". 

This means a Gadolinium rotor Stud may not experience cogging.

[synchro1]

Running the rotor vertically with the magnets at the base might permit us to capture and recirculate the heat with a fluid that would rise overhead from the heat, be cooled by the passing Gadolinium studs and sink to the bottem on it's own. MCE refrigerator parts might double for this appendage.

@Pirate88179,

The Gadolinium, Silicon, Germanium alloy developed by Ames has a currie point of 27º Fahrenheit.

Just need to find a cheap supply of that gadolinium.
